My 10yo wanted to be nice and took one of our hens to the field next door (about 3/4 mile from the coop) to forage. If I had known I would have forbidden it. She blinked and now our wellsummer is missing. We looked together for about 45 min until it got too dark. Since it's so far I don't think she will be able to find her coop on her own (correct me if I am wrong, please).
Our plans to look tomorrow include:
taking our most talkative hen out in a cat carrier and hoping the lost hen hears her and comes out
watching the field (it's wheat) for movement
blindly walking the rows looking for a feather in a straw field
Is there anything else we can do besides assume the worst?
